Cómo instalar el módulo de NetWorker para bases de datos y aplicaciones (NMDA) para Oracle en Linux.

La instalación de NMDA en Linux para respaldos de bases de datos de Oracle consta de dos pasos.   

• Instalación del software mediante RPM
• Vinculación de la biblioteca de Oracle de NMDA con Oracle  

1. Como usuario raíz, emita el comando RPM y asegúrese de que NetWorker lgtoclnty el paquete de cliente extendido lgtoxtdclnt se instalan en el host de Oracle. 

   rpm -qa |grep -i lgt
   lgtoclnt-19.14.0.0-1.x86_64
   lgtoxtdclnt-19.14.0.0-1.x86_64
   

2. Verifique que el proceso en segundo plano nsrexecd de NetWorker esté en ejecución e inícielo si no está activo.

   [root@nmda19-1 nsr]# ps -ef |grep -i nsr
   
   [root@nmda19-1 nsr]# systemctl start networker
   
   [root@nmda19-1 nsr]# ps -ef |grep -i nsr
   root      434734       1  1 15:59 ?        00:00:00 /usr/sbin/nsrexecd
   [root@nmda19-1 nsr]#

3. Descomprima y extraiga su bola de alquitrán NMDA descargada anteriormente.

   [root@nmda19-1 19.4]# gunzip nmda19401_linux_x86_64.tar.gz
   [root@nmda19-1 19.4]# ls
   nmda19401_linux_x86_64.tar
   [root@nmda19-1 19.4]# tar -xvf nmda19401_linux_x86_64.tar
   LGTO_METAFILE_linux86w_nmda.mf
   lgtonmda-19.4.0.1-1.x86_64.rpm
   sd_products.res
   [root@nmda19-1 19.4]#
   

4. Mediante el instalador de RPM, instale el software NMDA.

   [root@nmda19-1 19.4]# rpm -ivh lgtonmda-19.4.0.1-1.x86_64.rpm
   warning: lgtonmda-19.4.0.1-1.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c5dfe03d: NOKEY

   ***  Important information for completing your NMDA installation: ***
   ---------------------------------------------------------------------
   Depending on the database or application that you want to protect
   with NMDA, there might be additional postinstall steps you have to
   perform. Refer to the NMDA installation guide for instructions.
   
   ***  Important Information for Configuring NetWorker Module backups   ***
   -------------------------------------------------------------------------
   You can now start the NMC Backup Configuration wizard to configure the backups.
   To start the wizard:
   1. In your web browser, go to the URL of the console server
      http://nmc_server_name:9000 (the default port is 9000).
   2. Log in to the console server.
   3. Select the appropriate server name, click Launch NetWorker Administration
      in the right pane to start the NetWorker Administration interface.
   4. Click the Protection button, right-click Clients in the left pane, and
      select New or New Client Wizard from the menu.
   [root@nmda19-1 19.4]#
   

5. Conviértase en el usuario de Oracle (el usuario propietario del $ORACLE_HOME ) y cree un enlace simbólico a la biblioteca de NMDA.

    su - oracle
    cd $ORACLE_HOME/lib
    ln -s /usr/lib/libnsrora.so  libobk.so

     8. Valide que puede asignar un canal SBT mediante el nuevo NMDA biblioteca, conectándose a RMAN y ejecutar un script simple.

export ORACLE_SID=orcl    
[oracle@nmda19-1 config]$ rman target /
